Disassembly and assembly
Disassembling and assembling
turbocharger
If two turbochargers are mounted on an engine, one with a left-hand
and one with a right-hand oil inlet, a pin can be fitted in the bracket as a
precaution against incorrect positioning. This pin (B) locates in a corre-
spponing groove in the foot of the bearing casing.
Fasten the cartridge group using fastening strips (51002), Verbus
Ripp® washers (51003) and nuts (51007) (also see the chapter enti-
tled Table of tightening torques).
Fasten the bearing casing (42001) using the fixing screws (C).
Tighten the fixing screws (C) to the torques listed in the following table.
**) For the assembly of the turbocharger on the engine support, the
threads of the screws and screw heads must be lightly oiled (assumed
coefficient of friction µ = 0.12 for the tightening torque).
